In the' accompanying drawings; the ,preferred forni ofthe invention has been s n In said drawings :#fF igufr'e 1l is veitieal seetioii through the Iioftoi.'v F'g is an elevation ofthe xhoto with the o'apof the casing rerhoved. Figi 3 interior view of the cap. Fig. tis-a detail viewy of;

disk as well as the wall of the oasing'LSUleiS to support a guide sleeve 4 arranged a-Xially within and extending beyond the casing 1 and having a lining 6 of suitablezmetal in which an arbor 7 is journaled. One end of fiva'll of the Casing-1 as shown.

tlie'arb'i is preferably srew threaded, as indreated at 8, so -as to engage a flexible 'Shaft or the like t0 befdrive. This' threadsleeve 4i-loated Within the'f easing,L and is preferably tapered, as shown' at 9,`this tapered' end being adapted to be'k Vtoiiohed nightly by one end of a' spring strip 10,1;11@

Aother end of said strip being secured' to the This spring :servesto hold the arbor ag'ainst longitudinal f-di'sp'laoeinent Without however pressing upon it tof* an' objeotionable extent.

Secured to the arbor 7 is a disk l1 one iside of whieh bears against the sleeve 4 and ith@ lining wherein. This disk mangia-any formed', and as shown iii F ig. A4, has a s'ofal- Flo p'elv lizeriplie-ry from' which extend radial slits or incisions 1 2, there beingciroiilar il openings" 13 within the disk and at the inner fe'iids of these incisions. rvThose portions of f the disk bouded'by the incisionslQ andthe siillops at thepriphery of the disk, are

ii adapted to" be given a? one-quarter twist so as to form radiating blades 14, ne faoe of `each blade being eonoaved, as indieated in ly spoon shaped inasniue'h as rit, is con lengt-h ,and' in the direction of its width.

- aoholf the blades projects, at its inner end,

beyoiid the" side fabesof the disk y11 foi` the il purpose hereinafter set forth, but said projetinp'g-l iiineiiids of the blades are out away or open as shown, this being diie to `the fornialftjion of the circular openings 13 in the '1 disk.k

a portion of the/blank' fro'ih'- vvh'i'clthewheel' f leXtension 15: having a coupling 16 swiveled l thereon and adapted to be plated in engage- S'ecured upon the casing 1 is `a tubular In'i'entA with the threaded end of a faucet or the like. A small tube 1T,l constituting a 'discharge nozzle, is extended through the 4easing' 1 and opens a't` one endv intogt-he eziteiision' 1'5" while'its other end is'ad'apted' to fdireet a )et of water against the outer veX- Y.,'llhe open end of the kCasing is 'adapted to o be closed byineans of a senn-spherioal cap 1S the bottom portion of which is formed with'a number of outlet openings 19, a deflecting web 20 being arranged radially within the lower part of the cap and serving both to reinforce the cap and to control the swirling action of t-he water discharged into the casing and to direct it to the outlet openings 19. l

All parts of the casing as well as the wheel are to be stamped from comparatively thin sheet metal and it will be seen therefore that the complete device is very light. The web 20 serves to prevent buckling of the cap 18, as hereinbefore stated, and the casing l is furthermore braced by the disk 2, said disk cooperating with the casing to hold the sleeve 4: against displacement relative to the casing. Moreover the meeting portions of the casing and cap lap, as indicated at 2l, thus reinforcing the structure annularly.

In using the motor, the extension 15 is coupled to a supply faucet, pipe or the like and the water is directed from the extension 15 through nozzle 17 and against the middle portions of the outer terminals of the blades 14. By referring particularly to F ig. 1 it the nozzle occupies the same will be seen that plane as does the disk 11. The jet of water,

upon striking the outer end portion of al blade, will cause said blade, as well as the disk, to rotate with the arbor 7. Vibration of the wheel due to application of power at points removed from the longitudinal centers of the blades and to the discharge of unequal quantities of water from the two sides of each blade, is thus eliminated, any other vibration occurring as a result of other causes, being eliminated by the retaining spring 10.

It has been found that where a motor casing is formed of very thin metal shaped in the manner shown and described, a ringing sound is often produced, this sound being very objectionable. By providing a compartment between the disk 2 and the adjacent middle portion of the wall of the cas-j ing and leaving said compartment open by cutting away a segment of the disk, water is free to How into the compartment and keep it filled, thus deadening such ringing sound. When the water leaves the blades it is thrown outwardly by centrifugal force and a thin film of water is thus maintained upon the inner surfaces of the casing and cap. This water film positively eliminates the objectionable ringing sound.

In water motors of various types it has been customary to discharge the used waterv in a single stream from the casing. This, however, has produced an objectionable splashing sound. To eliminate this noise I f l the openings 19 have beenmproviided, these openings permitting the water to escape in small streams. The web 20, which is arranged adjacent the openings, serves to deflect the water film into the outlet openings, thus preventing the water from backing up in the casing and retarding the rotation of the-wheel.

IVhile the blank shown in Fig. 4 has circular openings formed therein, it is to be understood that these openings may be of any other shapes desired.

That is claimed is 1. A hydraulic motor, including a casing, a bearing member extending axially therein and therebeyond, an arbor mounted for rotation within said member, a wheel secured to the arbor and revoluble within the casing, said lwheel including radially extending spoon-shapedblades having outlets at their inner ends and located beyond the sides of the wheel, a nozzle for directing water successively against the outer end portions of the blades to rotate the wheel, a reinforcing disk connecting said bearing member to the casing and forming a dead water compartment between the disk and casing.

2. A hydraulic motor including a casing, a disk secured therein and having a marginal opening, a bearing member supported by said disk and casing, an arbor journaled within said member, a wheel revoluble with the arbor and having radially extended spoon-shaped blades, yielding means constituting a thrust bearing for the arbor, and a nozzle lfor directing water successively against the blades during the rotation of the wheel, said blades constituting means for directing the water outwardly to form a [ihn covering the inner surface of the casing.

3. A hydraulic motor including a casing, a bearing member extending axially therein and therebeyond, reinforcing means connecting said bearing member with the casing and cooperating with sai d casing to form a dead water compartment, an arbor journaled within said member, a wheel revoluble with the arbor, a nozzle for directing a jet of water successively against the blades of the wheel and a cap secured upon the casing and having a plurality of discharge openings.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
